The evolution of clothing towards functionalization and intelligence has led to increasing attention on wearable smart garments. In modern military combat systems, the smart sensing fabric plays crucial role in soldiers' combat attire. It possesses characteristics of perception, feedback, response, as well as the softness and wearability of textiles. This enables it to detect changes in the external environment and make corresponding adjustments to meet specific needs. In the military field, smart sensing fabrics can more comfortably and safely monitor soldiers health status while playing an important role in battlefield information perception, combat command, and other aspects. It can monitor soldiers' physiological states, environmental changes, and battlefield situations in a real-time manner, providing commanders with timely and accurate information support to enhance soldiers survivability and combat effectiveness. The smart sensing fabric integrates various types of sensors with fabric substrates to perceive and monitor various physical or environmental parameters, converting them into readable electrical signals. Featureing excellent flexibility, stretchability, and wearability, it is able to conform to various human body curves and irregular shapes, meeting the demands of different application scenarios, especially suitable for scenarios requiring flexible measurement of strain or pressure. This article systematically reviews the research progress in recent years on textile-based strain sensors, pressure sensors, temperature sensors and humidity sensors, and the application of smart sensing textiles in military equipment. It also analyzes issues such as data security, washability, stability, and reliability of data transmission. Therefore, the smart sensing fabric demonstrates tremendous development potential and diverse applications in the military equipment field, such as monitoring soldiers' physiological states, battlefield environments, and movement postures. As textile technology advances and intelligent technologies continue to evolve, smart sensing fabrics will achieve more innovations in materials, functions, and structures. They will not only become lighter, softer, and more comfortable but also integrate more sensors and intelligent components for more precise and comprehensive perception and monitoring.
